Problems solved by technology
[0003] During the use of existing bicycles, the front wheels and the rear wheels of the bicycle need to be braked separately when using the brakes, and the direction of the handlebars needs to be controlled when braking at the same time. This is not conducive to the safety of the user in some dangerous situations. Safe, at the same time, the existing hand brake, due to the wear of the brake pads, will cause the wheel to deflect during braking, making it difficult to control the direction of the bicycle, which will have a bad impact on the user

The invention discloses a bicycle with an air brake. According to the technical scheme, the bicycle with the air brake comprises a bicycle frame which is provided with a handle, a front wheel, a rear wheel, an installing rod and a saddle. The front wheel and the rear wheel are each provided with an axle. One side of each axle is connected with a braking assembly which comprises a braking part fixedly connected with the axle. An annular braking groove is formed in each braking part. The end, close to a fixing frame, of each braking groove is fixedly connected with a piece of elastic rubber which is in sealed connection with a braking pad groove. Each piece of elastic rubber is fixedly connected with a plurality of braking pads. A communicating tube is arranged on the wall face of each braking groove. Each braking assembly further comprises a fixing support fixed to the corresponding wheel. The fixing frames rotate around the braking parts correspondingly and are in sealed connection with the braking parts correspondingly. Each fixing frame is provided with one braking pad groove. A piston cylinder is arranged in the installing rod and communicates with the communicating tubes. A piston is arranged in the piston cylinder. The piston is connected with pedal plates, and a user can stamp on the pedal plates for compressing air conveniently. According to the bicycle with the air brake, the problems that an existing bicycle is uneven in braking friction force, and a front wheel and a rear wheel cannot be braked simultaneously are solved.
Description
technical field [0001] This invention relates to a bicycle, and more particularly to an air brake bicycle. Background technique [0002] A bicycle, also known as a bicycle or bicycle, is usually a small land vehicle with two wheels. After a person rides on the car, it is powered by pedals, which is a green and environmentally friendly means of transportation. The braking system of the bicycle is also different. The common one is the handbrake, and the other is the dead fly bicycle. Its rear axle is fixed so that it can be braked by stepping back with the foot. [0003] During the use of existing bicycles, the front wheels and the rear wheels of the bicycle need to be braked separately when using the brakes, and the direction of the handlebars needs to be controlled when braking at the same time. This is not conducive to the safety of the user in some dangerous situations. It is safe, and at the same time, in the existing hand brake, the wear of the brake pads will cause th...
